“Jackass” star Steve-O, now sober, sheds light on his zany crew’s hard-partying ways in an interview with TheFix.com. “[The cast] have never really hung out without a reason, except to get loaded,” the stunt maniac said. “And I don’t have any legit reason to be in a situation to watch those guys drink. The whole time we did that third movie, I never once did that.” Since cleaning up his act, Steve-O penned a memoir, “Steve-O: Professional Idiot,” and launched a stand-up act which he says doesn’t require “having to hurt myself or do anything demeaning.” “I don’t know what to say, except I love Ryan Dunn and I’m really going to miss him,” he Tweeted after the death of his “Jackass” castmate in a drunk-driving car wreck.
